T-56 Question

[GeoffP]

Is there a bushing in the tail shaft of the T-56 like there is in TH350/TH400 transmissions to support the output yoke? I'm getting some driveline vibration that I'm 99% sure is coming from a worn tailshaft bushing in the T-56 in my 68 Camaro. I'm trying to figure out how easy this will be for me to fix myself. I'm a fairly competent mechanic, so as long as I won't mess up any bearing pre-load etc by pulling the tail housing off, I'd like to fix it myself this Saturday. Hopefully someone in the know will chime in!

Thanks
